Title: Azeotropic distillation of benzene
IPC: C07C7/06
Filed: 1969-12-18
Abstract: Benzene is purified by (a) continuously supplying the impure benzene to a distillation column, (b) continuously supplying acetone to the column at a lower level than the benzene inlet the distance between the two inlets being at least 10 theoretical plates, (c) removing acetone with the impurities as the top product, and (d) discharging benzene with a lower impurity content as bottom product. Used for purifying aromatic fractions obtained by reforming and/or cracking, which contain non-aromatic hydrocarbons in addition to benzene. More efficient purification of the benzene is obtained.

Title: Plastic bag assemblies for rapid packaging of articles
IPC: B65D33/00
Filed: 1971-06-30
Abstract: A pre-assembled block of bags for rapid packaging of articles consists of a number of adjacent bags formed from oriented plastic film of longitudinal weldless tube arranged in flat form so that their opposing walls are in contact, welded transversely at one end and open at the other end, a series of coincident holes in the opposing walls being provided near the open end so as to form a continuous opening throughout the block, the holes having reinforced edges integral with the bag in order to avoid splitting. An oblong element passes through the holes in order to fix the bags in the form of a block. The bags may be formed from lay flat tubing of oriented polyolefins or biaxially oriented polyvinylidene chloride. The reinforced zones of the holes may be of non-oriented plastics and may adhere to one another. A tendency for the plastic material to shear between the holes and the open end of the bags is advantageous. The bags are easily formed, assembled and filled.

Title: Small batch domestic water still - having reflux condenser and cooling water tank mounted above boiler with gutter catching distillate
IPC: B01D5/00
Filed: 1972-09-04
Abstract: A water still, suitable for home or camp use, to improve smell and odour of water, and remove dissolved e.g. fluoride, and suspended solids, consists of a boiler discharging steam into a condenser wider than the hole through which the steam is issued. The condenser is surrounded by a tank of water, and condensate flows into an annular gutter at about the same level as the steam exit hole, and is run off. Water for topping up the boiler can be drawn, e.g. automatically, from the cooling water tank. The still consumes about 1 kw, and basic use of mechanical parts is avoided, and fur can be easily removed.
Patent NL-7317549-A (NL)
Title: I.C. engine exhaust pollution prevention system - maintains combustion temperature at level where pollutant level is acceptable
IPC: F02D13/02
Filed: 1973-12-21
Abstract: The quantity of harmful ingredients in the exhaust gases is limited by keeping the combustion temperature to a value where it is below the set level, typically by water injection controlled by a temperature detector in the cylinder, timing and duration being regulated dependent on the speed of the engine, so as to avoid pinking. The intake air can be heated, typically by means of the exhaust gas, to the temperature where the saturated vapour tension of the fuel gives the precise stoichiometric ratio for it. Where gas is used as fuel, the gas pressure can be reduced in a valve so as to produce saturated vapour tension in the fuel.

Title: Universal clamping frame for rods reinforcing concrete slab - also lowers assembled rods from pivotted arms into anti:corrosion bath before fixing
IPC: B28B23/02
Filed: 1975-12-16

The cross beams carry bearers for the reinforcing rods. The bearers can project from the cross beams to any desired depth, to suit the thickness of the slab being made. At each end of the welded steel frame (10) is pivoted an arm (14) on which the frame with assembled rods can be lowered to dip the rods into an anti-corrosion bath. The assembled rods are then kept in the frame for transport to the site where they are fixed.

Title: Cooler for boxless moulded castings and moulding sand - has switch diverting cold, possibly empty moulds through by-pass
IPC: B22C5/08
Filed: 1976-12-17
Abstract: An installation for cooling castings and cooling and drying the moulding sand, comprises a driven drum, free to rotate on bearings, with an inlet for boxless moulds. These are delivered to it by a conveyor, and at the rear end of the drum there are outlets for the sand and the mouldings. A bypass outlet is also provided in which there is a breaker for compacted lumps of sand. This overcomes the problems occuring when the heat of the drum is reduced so taht the fluidity of the sand is also reduced and the drum is filled to a higher level than that for which it is designed.
Patent NL-7702817-A (NL)
Title: Cross reference system of data by difference balance - uses automatic or computerised system for high speed with accelerations due to unidirectional motions
IPC: G07C15/00
Filed: 1977-03-16
Abstract: A faultless cross referencing method when the given data for this purpose rounded off in the combination in the proof is established as corresponding correctly. It is achieved by drawing up a balance where the differences exceed the equalities. The assessment is carried out in a logical form. The system is operated by a specially designed fully automatic or computerised mechanical system and it is electronically driven to achieve higher speeds of operation. There will be accelerations given that movements can be obtained in all directions because of the rapid reflections. All the references will always have differences and will therefore be incorporated in the balance.

Title: Memory controlled switching circuit - uses computer-controlled RAMs or EPROM(s) to make connections between input and output lines
IPC: H03K19/177
Filed: 1980-02-07
Abstract: This switching circuit makes connections between five input lines and five output lines under the control of memory circuits.

Patent NL-8702901-A (NL)
IPC: A01C23/02
Filed: 1987-12-02
Abstract: Device for the injecting of liquid manure into the ground. A very narrow cut is made in the ground of for example grassland by vertically disposed pairs of blades (7). Directly at the contact point between the blades debouches a nozzle (13) that is connected to a reservoir for liquid manure. Thus achieved is that the liquid manure is introduced directly into the narrow cut in the ground, after which the cut is closed up again by a following furrow closer. This prevents environmentally damaging ammonia escaping from the liquid manure into the surrounding air.

Title: Selection using opine synthase genes
Inventor: DAHL GARY A
IPC: C12N15/04
Filed: 1984-09-11
Abstract: During the past ten years, the ability to splice DNA from a variety of sources into a recombinant DNA molecule and then to transfer such DNA molecules into different species of prokaryotes and eukaryotes has led to the most exciting revolution in the history of biology. Most of this work has involved the use of bacteria, fungi and animals. Plants have been relatively neglected primarily because suitable vectors were not available. Recently a number of possible vectors have become available but in their natural state they have not been efficient in the transfer and expression of genes from various sources to plant species. The present invention describes some novel discoveries which increase the usefulness of naturally occurring plant DNA vectors in the genetic engineering of plants.
